Symptom narrative

Arrhythmia; Chest pain; worse with deep breathing; Painful respiration; sinus tachycardia; Tachypnoea; Electrocardiogram ST segment elevation; Electrocardiogram T wave normal; Electrocardiogram repolarisation abnormality; Fibrin D dimer increased; QRS axis abnormal; Myocarditis is highest concern given elevated troponins; Cardiac monitoring; Anaphylactic reaction; Initial information received on 28-Apr-2026 regarding an unsolicited valid serious case received from a consumer (non-healthcare professional). This case involves a 16-year-old male patient who had arrhythmia, chest pain, worse with deep breathing, painful respiration, sinus tachycardia, Tachypnoea, electrocardiogram (ECG) ST segment elevation, electrocardiogram T wave normal, electrocardiogram repolarisation abnormality, fibrin D dimer increased, QRS axis abnormal, myocarditis is highest concern given elevated troponins, anaphylactic reaction and cardiac monitoring after receiving meningococcal A-C-Y-W135 (T CONJ) vaccine (MENQUADFI). The patient's past medical history, past drugs, vaccination(s), family history, and concomitant medications were not provided. On 18-Oct-2024, the patient received dose 2 of suspect meningococcal A-C-Y-W135 (T CONJ) vaccine (MENQUADFI) solution for injection, batch : U8370AA (expiry date and strength: unknown) via intramuscular route in the right arm for prophylactic vaccination (Immunisation). On 19-Oct-2024 patient had worse with deep breathing (Dyspnoea), Myocarditis was the highest concern given elevated troponins (Troponin increased), was currently hospitalised on cardiac monitoring, chest pain, sinus tachycardia, Tachypnoea, arrhythmia, painful respiration, electrocardiogram (ECG) ST segment elevation, electrocardiogram T wave normal, electrocardiogram repolarisation abnormality, Fibrin D dimer increased, QRS axis abnormal, anaphylactic reaction (all with latency: 1 day). Relevant laboratory test results included: Troponin - On 19-Oct-2024: elevated troponins, currently trending down Tachycardia - On 19-Oct-2024: 104-140 (units unspecified) D dimer - On 19-Oct-2024: 816 (units unspecified) tachypnea On 19-Oct-2024 :22-32 (units unspecified) Electrocardiogram - On 19-Oct-2024 : latest result at 1539 - sinus tachycardia, borderline right axis deviation [QRS axis > 90], ST elevation, probably early repolarization [ST elevation with normally inflected T-wave], abnormal rhythm ECG labs (elevated troponins and D dimer). Echo read pending, chest xray and chest ct has been performed with results are pending. Reportedly, Pt presents with father for chest pain since 19-Oct-2024, worse with deep breathing, denies SOB, denies trauma, denies worse pain with palpation. Action taken: Not applicable Corrective treatment: Not reported for all the events. Event outcome: It were reported as not recovered/not resolved/ongoing for all the events. Seriousness criteria: Caused/prolonged hospitalization for all the events.
